SAULT STE. MARIE, Mich. — The Coast Guard is advising residents of Alpena, Mich., that the commercial tug Manitou is scheduled to break ice in the Alpena Harbor near the LaFarge facility, beginning Wednesday afternoon.

The ice-breaking operation does not involve a Coast Guard icebreaker; nonetheless, the Coast Guard is advising residents and visitors that any ice in the area may be particularly unstable and dangerous.

Ice fishermen are asked to remove their ice shacks and equipment from these areas.

All transit times and locations are subject to change based on weather conditions.

All efforts are being made to limit the impact on winter activities on the ice, however the Coast Guard advises everyone to stay clear of this area.

Anyone participating in ice activities on the Great Lakes should follow the acronym of I.C.E.:

* Information about current weather and ice conditions. Tell a friend of your intended destination. Know who and how to call for help.

* Clothing that is appropriate for the activity. Dress for the water temperature, not the air temperature. Choose bright colors and reflective garments to aid searchers if you should end up needing help.

* Equipment to be safer on the ice. Always bring a life jacket, a compass or GPS, a means of communication, such as a marine radio, and screw drivers or ice picks, which may allow you to pull yourself out of the water should you break through.
